GRAIN DGOR.

Application tiled Ianuary'lf, 15324V Serial No. 685,86.

u To all whom it may concern:

. porting ,grain or the like.

The primary object of the invention is to provide means forautomaticallyL folding and supporting the upper sections of grain doors,when the doors have been moved to 4 their open positions.

v Another important object of the invention is to provide a novel formof operating means which may be readily and easily operated from a pointextcriorly of the car, the operating means beingsuch as will hold thedoors in various positions of adjustment.

lll'fithy the foregoing and other objects in view which will appear asthe description proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawings:

Figure 1 is a front elevational View disclosing a car door constructedin accordance with the present invention.

Figure 2 is a vertical sectional View through the car and door openings.

Figure 3 is an elevational view of the cable operating mechanism.

Figure 4 is a front elevational view thereof.

Figire 5 is a sectional detail view dis closing the manner of securing,rthe handle to the operating means.

Referring to the drawings2 in detail, the reference character5dcsignates a car which is supplied with thusiial. openings. Tracks 6are secured adjacent to the side edges of the door openings; andasshown, each of these tracks includes an upper horizontal section 7. Y

Each ofthe doors includes a lower section 8 and an upper hinged section9,c the lower section being supplied with rollers 10 adje` cent to itsupper and lower edges, the rollers extending laterally from the doorsection to the position in the tracks so thatthe door will be heldagainst` lateral movement at all times.

The upper section 9 ot each door, is relatively narrow and is held toits active position by the weight of the grain within the car. Brackets11 are secured to the ceiling of the car and are arranged at pointsadjacentto the sides of the car doors, but centrally of the ceiling.Rods 12 connect. the brackets and provide supports for the rollers 13that lic in the paths ot travel of the upper sections 9 of the doors,when the doors are moved to 'their open' or inactive positions, to theend that es Ithe sections 9 engage the rollers, they will he foldedtowards the lower section 8 of the door, and supported adjacent to theceiling of the car. 1

Associated with each door is an operating mechanism which includcsecable 14 secured to the door at a point adjacent to the lower end of thedoor, from where the cable passes over the pulley l5 disposed adjacentto the upper end of the door, the cable passing over the pulley 16arranged laterally of the door. The cable also passes over pulley 17mounted in the support lS secured to the outer surface of the car, i romwhere the pulley passes onto the drum 19 mounted within the housing 20.

Supported `on one end of the shaft that supports the drum 19 is a gear2l that oper ates in the casing 2l that may be partially filled withgrease to lubricatc the gearing.

The naar is operatedliv tlievorn'i Q2 can ried by the shaft 23, whichshaft is supplied with an operating handle Q4 that has :i squaredextremity 25 to bepositionedin the squared 4opening.: of the member 26forming a part of the handle.

In order that the member 26 may be non mally held to the handle 24, acoiled spring 27 is provided. which spring has connection with thehandle 24 at 28. the lower end of the coiled spring being connected tothe 'member 26 so that the contractile force of the spring will tend toprevent displacement of the member 2G. From the foregoing it will beobvious that it' it'is desired to move the member, 2G to its inactiveposition, the

memberrnay by forcin the same downvvardly,` be disconnected rom themember 24 and slightly turned to a, position to bring the member 20 to apoint under the ear proper and out of lthe Way of persons walking "nearthe car.

In operation, whenthe handle is operated,` the cable will be Wound onthe drum 19l and the door associated therewith, moved upwardly, theupper sectiono'f the door engaging the roller 12 associatedtherewth tothe end that the upper section .is folded rearwardly and the lowermostSettion moved to overlie the upper section. y

`I claim?" 1. In a car door construe-tion, a trackway th'e -uppersection to swing rearwardly, and means for moving the door te its`active and inactiveV positions.V

2. In a car door construction, a trackway positioned adjacent t0 thedoor opening, n door movable in the trnckway, seid door ineluding anupper hinged section, bracket.

members within the ear and arranged adjacent to the upper ends of thetraekway,

lying in tie path of travel of the door -to its 'open osition, saidrollers adapted to support tie upper hinged section inA its openposition, and means for operatz the door.

In testimony that I elmni the ouegong. as

my own, I have hereto affixed my signature in the presenee of twowitnesses, v Y HENRYY KALER. Y Witnesses:
